Fistula is a medical term, used to describe abnormal connection between two organs.

If this occurs in the gut, it is called gastro-intestinal fistula.

Gastric acid and intestinal fluids usually flow out through this abnormal opening that may result in severe infection.

It's not uncommon that infection spreads all over the body, including the blood, leading to strong immune response. It usually becomes apparent in high fever, rapid breathing, increased heart rate, low blood pressure and polyorganic dysfunction. If not treated quickly, sepsis becomes an extremely dangerous, life-threatening event.

In vast majority (nearly 85%) of cases, gastrointestinal fistula happens after surgical procedures in the belly.

Internal fistulas cause connections inside abdominal cavity or thorax. Intestinal fistulas are openings between two different parts of the gut. If fluids leak from the gut into other body organs (bladder, lungs or even vessels), it is known as extraintestinal fistula.

In some cases, connections appear in different organs at the same time. Doctors call them complex fistulas.
